Poly[(μ₃-1,1-dioxo-1,2-benzo­iso­thiazole-3-thiol­ato-κ³N:S³:S³)silver(I)]

The centrosymmetric title compound, [Ag(C₇H₄NO₂S₂)]_n, consists of dinuclear units in which two thio­saccharinate anions each bridge two Ag atoms via an endocyclic N atom and an exocyclic S atom across a crystallographic centre of inversion midway between the Ag atoms. The dimeric units are connected via Ag—S_exo inter­actions to create two-dimensional networks. The thio­saccharinate anions bridge in a μ₃-S:S:N manner. The Ag...Ag distance can be considered a strong argentophilic inter­action.
